In terms of XPath there is no relation between those col elements and 
their values and the td elements.
You can however access the td elements by their position e.g.
   /table/tr[td[1] = 2]/td[2]/text()
selects the text content of the second td element in the tr element for 
which the first td element has the content 2.
